I'm following the tutorial on how to do object detection using opencv 3.4 and mobilenet, but I have a problem when runnning this error appears, I already have created the graph.txt from the .pb file.

OpenCV Error: Assertion failed (!_aspectRatios.empty(), _minSize > 0) in cv::dnn

Please add more details. The source of the model, references to tutorial and all the mentioned files. Otherwise that question looks like "I can't load a .PNG image". Thank you!

Is the exact source as in the tutorial. I'm following this tutorial: https://github.com/opencv/opencv/wiki..., I've used both MobileNet 1 and 2.

I have the same problem at forward stages.

@pedrolima, @MinxiangLiu, Unfortunately, I can't reproduce it. TensorFlow 1.4.1, OpenCV 3.4.0-dev (revision https://github.com/opencv/opencv/comm...). ssd_mobilenet_v1_coco_2017_11_17.
